Executive Summary
This full reverse costing study has been conducted to provide insight on technology data, manufacturing cost and selling price
of the STMicroelectronics SCT30N120 1200V SiC MOSFET.
The STC30N120 is the first generation 1200V SiC MOSFET device from STMicroelectonics. The device presents a planar
structure and a design which allows good electrical performances; such as high current density. Moreover, the supply chain
and the manufacturing choices makes a very competitive cost.
The device is suitable for high power applications like motor drives, inverters, DC-DC converters and power supply.
The STC30N120 integrates the first generation high-voltage SiC power MOSFET dies in a specific discrete package.
STMicroelectronisc says that the components It offers a higher operating temperature (up to 200°C) and an On resistance of
90mohm for a very competitive cost. Il y a pas des differences des deisgn
The report goes into depth in its analysis of the packaging and the components, with images of the complex planar SiC
structure.
It also includes production cost analysis and overall comparison with Rohm and Wolfspeed SiC MOSFETs and with 1200V Si
IGBTs.
